The war started on February 28. By Wednesday, you felt it at the pump.
Less than two weeks after the United States joined Israel in military strikes against Iran, the cost of filling a gas tank has become one of the most visible domestic consequences of that decision. By March 11, the national average reached $3.58 a gallon — the highest since May 2024 — as disruptions to the Strait of Hormuz sent shockwaves through global energy markets with a speed that bypassed diplomacy entirely. The gap between a presidential promise to lower energy costs and the reality now facing American families is nearly 60 cents a gallon, and the forces driving it show no sign of relenting.
- Ships are still being struck in the Strait of Hormuz, and every incident tightens the grip on a waterway that carries a significant share of the world's oil supply.
- Wholesale gasoline prices surged by double digits on Wednesday alone — and those increases typically reach the pump within 24 hours, meaning Thursday morning could bring another painful number.
- The IEA's announcement of a record 400-million-barrel strategic reserve release failed to calm markets, offering no specifics on timing, contributors, or volume — raising more questions than confidence.
- The annual transition to costlier summer-grade fuel is converging with wartime supply pressure, compounding the squeeze on consumers at the worst possible moment.
- For small businesses, working families, and every sector touched by fuel costs — trucking, agriculture, retail — the financial strain is already present and accelerating.
- With midterm elections in November, the distance between Trump's 2024 energy promises and the current pump price is becoming a political liability as visible as the number on the sign.
By Wednesday morning, Americans were paying $3.58 a gallon for gasoline — the highest price since May 2024, and one that carries the unmistakable fingerprints of a war that began less than two weeks earlier.
On February 28, the United States joined Israel in military strikes against Iran. Within days, the consequences appeared not on a battlefield map but at gas stations across the country. Tracking data from AAA and GasBuddy showed the national average had risen nearly 60 cents since that decision. The speed of the increase is as striking as its size.
The mechanism is the Strait of Hormuz. Disruptions to that narrow, critical waterway — where more ships were struck on Wednesday — send immediate shockwaves through global energy markets. Wholesale prices were already registering double-digit increases, and those changes typically reach the pump the following day. As one small business lender put it, geopolitical shockwaves don't take months to reach your wallet. They take days.
More increases are expected. The United States is also entering its annual transition to summer-grade gasoline, a cleaner-burning fuel that costs more to refine. The two pressures are converging at the worst possible moment for consumers and for a president who won re-election in part on a promise to bring energy costs down, with midterm elections now eight months away.
An IEA proposal to release a record 400 million barrels from strategic stockpiles did little to reassure markets — analysts noted it lacked any specifics on timing or national contributions. Crude oil prices continued rising regardless. With the strait still contested and the summer fuel transition still ahead, the near-term picture offers little comfort to anyone watching the number on the pump.
By Wednesday morning, the number on the pump had climbed to $3.58 a gallon — the highest Americans had paid for gasoline since May of 2024, and a figure that carries the fingerprints of a war that started less than two weeks ago.
On February 28, the United States joined Israel in a military assault on Iran. Within days, the consequences began showing up not on a battlefield map but at gas stations from Maine to California. According to tracking data from AAA and GasBuddy, the national average retail price of gasoline has risen nearly 60 cents since that decision was made. The speed of the increase is the story as much as the size of it.
The mechanism is the Strait of Hormuz, the narrow waterway through which a significant share of the world's oil supply moves. Disruptions there — and on Wednesday, more ships were struck in the strait — send shockwaves through global energy markets almost immediately. Spot and wholesale gasoline prices were already registering double-digit increases on Wednesday, according to Denton Cinquegrana, chief oil analyst at Oil Price Information Service. Wholesale price changes tend to show up at the pump the next day.
William Stern, the chief executive of Cardiff, a small business lender based in the United States, put it plainly: geopolitical shockwaves don't take months to reach your wallet. They take days. You feel the squeeze the moment you fill up the tank to drive the kids to practice.
That kind of language — immediate, domestic, mundane — is exactly what makes this story politically combustible. Donald Trump won re-election in 2024 in part on a promise to bring energy costs down. The midterm elections are in November. The gap between that promise and the current reality at the pump is now nearly 60 cents a gallon and widening.
More increases are expected. Beyond the war's direct pressure on supply, the United States is also entering its annual transition to summer-grade gasoline, a cleaner-burning fuel that costs more to refine. The two forces are converging at the worst possible moment for consumers.
Crude oil prices — the largest single component of what you pay at the pump — were also rising on Wednesday, even after the Paris-based International Energy Agency announced a proposal to release a record 400 million barrels from strategic stockpiles held by member nations. The announcement did little to calm markets. Cinquegrana noted that the IEA offered no specifics: no breakdown of which countries would contribute, how much each would release, or when any of it would actually move. The proposal raised more questions than it answered.
The broader economic stakes are real. Fuel costs touch nearly every sector — trucking, agriculture, manufacturing, retail — and a sustained spike has the potential to slow economic activity at a moment when the global economy is already absorbing the shock of an active military conflict in one of the world's most critical oil corridors.
For now, the number to watch is what happens at the pump Thursday morning, when Wednesday's wholesale price surge works its way through the system. If the pattern holds, it won't be pretty. And with the Strait of Hormuz still contested and the summer fuel transition still ahead, there is little in the near-term picture to suggest relief is coming soon.

Geopolitical shockwaves don't take months to hit your wallet. They take days — you feel the squeeze the moment you fill up the tank.— William Stern, CEO of Cardiff, a US small business lender

The Hearth Conversation Another angle on the story
Sixty cents in less than two weeks — is that actually unusual, historically?
It's fast. Most price spikes of that magnitude take months to build. This one happened in days, which tells you how directly the market is pricing in the Hormuz disruption.
Why does the Strait of Hormuz matter so much? Can't oil just go another way?
Not easily. A huge share of Middle Eastern oil exports moves through that strait. Rerouting around it adds weeks and significant cost. Markets don't wait for the rerouting — they price in the uncertainty immediately.
The IEA announced a 400-million-barrel release and prices still went up. What does that tell us?
It tells you the market didn't believe it. The announcement had no specifics — no countries named, no timeline, no quantities per member. A vague promise of supply doesn't offset a concrete disruption.
How exposed is Trump politically here?
Quite exposed. His 2024 campaign made lower energy costs a centerpiece. Voters who chose him partly on that promise are now paying nearly 60 cents more per gallon than they were two weeks ago, because of a war his administration chose to enter.
Is the summer fuel transition a big deal on top of all this, or is it a minor factor?
In a normal year it's a manageable seasonal bump. Layered on top of a supply shock, it removes one of the few buffers that might have softened the increase. The timing is genuinely bad.
Who absorbs this hardest?
People who drive to work and can't reduce their mileage. Small businesses that move goods. Anyone operating on thin margins where fuel is a line item they can't cut.
